Macroalgae question

[Ptpro1]

Just received some Ulva in the mail for my refugium. Some of the leaves are green and healthy but some are red but look healthy. The red leaves are a solid color. Is there a red variety or are the red leaves actually green ones that are dying?

Thanks

Also, what is a reasonable quarantine time for macroalgae? Standard 2-4 weeks or just long enough to wait for any die off?

Hi Ptpro1 and :welcome: to TR.

I am a big proponent of QT so I would go at least 2 weeks.

And the refugium is not a quarqantine as I have seen many do.
